I purchased Tuesday, have had confirmation but no tickets (checked junk).
Email confirmation says that if you have any queries regarding order to email ticket office.
Website comms regarding Luton Town home game states that "phone lines and email inboxes will be closed during sales period" and go to Stadium of Light to speak to someone in person.
This leaves your average full-time worker Saturday to get to the ticket office to resolve issues like this.
I'm all for digitalisation and modernisation but to have no means of modern, digital customer support in the lead up to 45k+ "customers" descending on your establishment is criminal.
